Overhead line design is the core activity, for both transmission and distribution networks. Whether the project is a 400kV transmission line or an 11kV pole line, our well qualified and experienced team deliver design services
The Energyline civil engineering team support the delivery of overhead line projects, substation projects and cables projects, but it also offers stand-alone civil engineering services for projects that are not directly associated with the Power Systems industry.
By utilising our experienced in-house overhead line technicians who hold current authorisations for NGT and various DNO’s throughout the UK, we are able to provide a range of services that support asset condition assessments of towers and wood poles, below are examples of some of the services we offer.
Delivering a refurbishment project for Scottish & Southern Energy, Energyline completed over 100 kilometres of ground based precision surveys on overhead lines across varied and challenging terrain in the North East of Scotland, incorporating selected areas of LiDAR survey where conventional survey access proved impossible.
The distribution network operator Client required designs to be prepared for the proposed OHL modifications, Cable Sealing End Compounds (CSEC) and associated cable system on a double circuit 132kV overhead line near Aberdeen.
Energyline have supported the type registration schemes for both Aluminium Conductor Composite Core (ACCC, CTC) and Aluminium Conductor Composite Reinforced (ACCR, 3M). Our involvement included developing the type test regime in the absence of a wholly applicable UK standard, test witnessing and factory audits.
Energyline have been a key contributor to Scottish and Southern Electricity Network’s (SSEN) successful Network Innovation Competition (NIC) proposal to develop a New Suite of Transmission Structures (NeSTS)
We are currently taking the planning lead working across a multidisciplinary team of this proposed 100MW energy from waste scheme including district heat and power connections north of Scunthorpe. This role includes liaison and consultation with key stakeholders and the Planning Inspectorate.
Energyline’s team coordinated the discharge of a number of Requirements related to the Hinkley Point overhead line connection Development Consent Order for Stage 8, as well as preparing and submitting applications for all environmental licences and permits required to enable the construction team to commence work on site.
On behalf of Scottish Power Energy Networks we provided an integrated service package all delivered by our in-house staff. Including ground based visual inspection of all towers on the route, geotechnical desk study and intrusive foundation inspections.
Utilising our in house Cormon testing equipment we have surveyed a vast number of routes across the WPD network to assess the condition of the conductor systems, working independently we receive permits, earth the towers and land the equipment on the conductor.
Energyline were engaged throughout the project by our client Scottish & Southern Electricity Networks to climb and inspect all towers over a 12 month period, works involved checking new build towers and conductor system in accordance with the project technical spec. Findings were reported back into the client and contractor with supporting reports and photographs. Beauly – Denny was the largest construction project of its type in Scotland to date.
